[Nagiosplug-help] check_smtp problem

[morgan]

Hey,

Im having a problem with check_smtp and a Exchange (its not my choice), im
getting a response "SMTP OK - 0 second response time" from the plugin but
when I try to do a -e or --expect=SMTP OK - 0 second response time I get a
Invalid SMTP response received from host

Any insight would awesome

Thanks
Morgan
